摘要： An internal but not integrated security token is provided for a device which includes a first integrated circuitry including a secure processor. The security token is provided by a second integrated circuitry separate from the first circuitry. The second integrated circuitry includes a secure non-volatile storage. The secure processor communicates information to the second circuitry in a secure manner for the secure information to be securely stored in the secure non-volatile storage, and the second integrated circuitry communicates information stored in its secure non-volatile storage to the secure processor in a secure manner. Communications is secured by means of cryptography. The first integrated circuitry and the second integrated circuitry are internal parts of the device. An initialization method for distributing a secure key to be shared between the circuitries and to be used in cryptography is also disclosed.

摘要： State information necessary to maintain securely is saved on a probabilistic basis onto a flash memory of protected memory chip. The protected memory chip has a communication logics that prevents access to the flash memory unless appropriate cryptographically protected instructions are given. By saving data on a probabilistic basis, the aging of the flash memory can be reduced so as to inhibit malicious destruction of the flash memory. The communication logics can also address different parts of the flash memory selectively so that any time the state information changes, something is written to the flash memory. To yet avoid premature aging of the whole flash memory, a dedicated disposable portion can be used for normal writing so that the remainder of the flash memory remains operable. Corresponding security circuitry, assembly module and computer programs are also described.

摘要： A system and method for enforcing digital rights management (DRM) rules in a terminal, even when the requesting rendering application is already operating. Content, which may be encrypted, is received at the terminal and securely stored. On-demand authorization is effected for the rendering application that is requesting access to the content, using secure communications between a DRM engine within the terminal and an operating system within the terminal that is augmented with a security manager adapted to engage in such secure communications. If the rendering application is found to be authorized, the DRM rules are applied to determine whether the rendering application may access the content, and if so, the content is made available to the rendering application.
